Parameters

    • Type - The vector math operator to be applied on the input vectors.
      • Add - The sum of A and B. 
      • Subtract - The difference between A and B. 
      • Multiply - The entrywise product of A and B. 
      • Divide - The entrywise division of A by B. Division by zero results in zero. 
      • Multiply Add - The entrywise combination of the multiply and addition operations. 
      • Cross Product - The cross product of A and B. 
      • Project - The projection of A onto B.
      • Reflect - The reflection of A around the normal B. B need not be normalized.
      • Refract - For a given incident vector A, surface normal B and ratio of indices of refraction (IOR), refract outputs the refraction vector R.
      • Faceforward - Orients a vector A to point away from a surface B as defined by its normal C.
      • Dot Product - The dot product of A and B. 
      • Distance - The distance between A and B.
      • Length - The length of A. 
      • Scale - The result of multiplying A by the scalar input Scale. 
      • Normalize - The result of normalizing A. The result vector points to the same direction as A and has a length of 1. If A is (0, 0, 0), the result is (0, 0, 0) as well.
      • Absolute - The entrywise absolute value of A.
      • Minimum - The entrywise minimum value from A and B.
      • Maximum - The entrywise maximum value from A and B.
      • Floor - Rounds the input value entrywise down to the nearest integer.
      • Ceil - Rounds the input value entrywise up to the nearest integer.
      • Fraction - Returns the fractional part of the value entrywise.
      • Modulo - The entrywise modulo of A by B.
      • Wrap - The entrywise output of a value between Min and Max based on the absolute difference between the input value and the nearest integer multiple of Max less than the value.
      • Snap - The result of rounding A to the largest integer multiple of B less than or equal A.
      • Sine - The entrywise Sine of A.
      • Cosine - The entrywise Cosine of A.
      • Tangent - The entrywise Tangent of A.
    • Vector# - The inputs of the node are dynamic. Some inputs are only available in certain operations. For instance, the Scale input is only available in the Scale operator.
